RUFFLING DEVICE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented .Tune 22, 1909.

Application filed February 6, 1908. Serial N o. 414,464.

To all 'whomfit may concern.'

Be it known that I, FREDERIC M. CARD, a citizen of the United States,residing at Bridgeport, in the county of Fairlield and State ofConnecticut, have invented certain new and useful Improvements inRuilling Devices for Sewing-Machines, of which the followingis aspecication, reference being had therein to the accompanying drawings.

This invention relates to improvements in ruiiling devices for sewingmachines, and has for its object to provide means for gathering andattaching the ruilling strip to a garment or main portion of material ata single operation, through the employment of a seam consisting ofzigzag stitches.

Referring to the accompanying drawings, in the several gures of whichlike parts are similarly designated, Figure l is a front side elevationof a zigzag sewing machine, commercially termed Wheeler & lVilsonequipped with my improved mechanism. Fig. 2 is a view in perspective ofthe front end of the overhanging arm and bed-plate of the sewingmachine, together with a like view of my improved mechanism. Fig. 3 is aview in front end elevation of the overhanging arm, together with myimproved mechanism. Fig. 4 is a view in cross section substantially onthe line A-B, Fig. 3. Fig. 5 is a view in front side elevation of myrufliing device, together with a portion of the cloth presser bar andneedle bar. Fig. 6 is a view illustrating a portion of the finishedproduction, the arrow indicating the direction of the feed of thematerials under the needle. Y

In describing my improvement, only such limited reference will be madeto the usual well-known parts of the sewing machine as is deemednecessary for a proper understanding of the invention.

2 is the bed-plate of the sewing machine, l the overhanging arm, 6 thearm standard, 8 the band wheel, and 10 the needle-bar actuating shaft,the latter being operatively connected, by kthe commonly employedquartering cranks (not shown), with the lower or loop-taker drivingshaft l2.

14 is the loop-taker, operatively connected, through the commonlyemployed gears (not shown), with the lowerl driving shaft 12, whichshaft acts, through the commonly employed connections including the feedrock-shaft 16 and crank 1S, to transmit feed movements to the feed-dog20.

22 is the throat-plate, 2li the front slide plate, 2G the back slideplate, and 28 the take-up cam, the latter being' mounted upon theforward end of the shaft l() and provided with a cam groove 30 whichcoacts with a cam follower 3l to transmit movements to the take-up 32.

34@ is the needle-bar which is connected, through the needle-bar link 3Gand cam 2S, with its actuating' shaft 10 and mounted to move in theswinging frame 3S in different vertical planes.

40 is the cloth-presser bar mounted in bearings 42 and ltformed in theoverhanging arm and provided with the usual spring i6 and lift collar4S, the latter being acted upon by the presser-bar lift lever 50 to movethe cloth-presser bar in opposition to the resiliency of the spring 46.

52 is a segment lever pivoted to the overhanging arm at 54: and providedat its lowerend with the usual cam follower (not shown) which tracks inthe cam groove 5G of the switch cam 5S which, in turn, is secured uponthe shaft l0.

60 is a segment lever connection pivoted at one end to the swingingframe 38, its opposite end being provided with the usual adjustableconnection G2 through which said segment lever connection may beadjustably secured at any point in the groove 641 of the lever 52, thus,through the action of the switch cam 5S, transmitting swinging movementsto the gate SS'and positioning the needle-bar to be moved in differentvertical planes, as in the formation of zigzag stitches. i

The swinging gate 3S is pivoted upon pintle bearings 6G and G8 threadedinto the overhanging arm and held against accident-al movement by therespective nuts 70 and 72.

7 is the arm face plate provided with the usual thread controller 76,thread tension device 7 8, thread check SO, thread leader S2 and tensionrelease lever 84.

All of the foregoing descriptive mattei' pertains to commonly employedmeans which may be as herein pointed out or of any other approved formof construction for giving to the needle its vertical and lateralmovements and for advancing the material to the action of thestitch-forming mechanism.

86 is a ru'tlier trame mounted in a slot 88 formed in the lower end otthe presser-bar and secured by screw 90.

92 is a rutliing blade lever pivoted at 94 to the frame 86 and carryingat its lower end a rutlling blade 96 which is secured to said lever byscrews 98, 98.

100 is an operating lever comprising arms 102 and 104, said lever beingpivoted byy a screw 106 to the frame 86. The arm 104 is provided with anopening 108 through which passes a stud screw 110 threaded into an arm112 of a bracket connection 114, said connection being secured by ascrew 116 to a lug 118 depending from the needle-bar bearing 120, saidbearing and lug forming integral parts of the swinging frame 38.

122 is a connection, one end of which is pivotally connected at 124 withthe arm 102, its opposite end being rovided with an adjustableconnection 126 for varying the adjustment of said connection relativelyto the slot 128 formed in the lever 92.

130 is a cloth-presser of the usual construction which, in the presentinstance, forms an integral part of the frame 86.

132 is a base plate adjustably secured, relatively to the needleactuation, by a screw 134 which passes through the slide plate 26 andis-threaded into the bed-plate 2, said base plate being provided with astripper blade 136 which extends beneath the ruffling blade 96. Theplate 132 is provided with a gage plate constructed in the form of aloop and comprising the members 138 and 140, and between said members isadjustably mounted, by screws 142 and 144, an edge guide 146. The member140 is provided with a lip or plate 148 which rests against the throatplate 22 and over which the body portion of the material travels, andwhich acts to insure a smooth and uninterrupted guidance of the edge ofthe material along the edge 150 of the gage plate. Vhile the plate 148is considered desirable, it is not essential to the practical operationof the device.

The body portion 152 of the stud screw 110 is of sufficient length topermit the presser 130 to be raised without the end 154 of the arm 104contacting with the head of the screw 110.

rIhre operation of the device is as follows The ruttling strip 156 ispassed through the opening 158, between the ruiiiing blade 96 and thestripper blade 136, and then beneath the presser-foot 130. The mainportion of the material 160 is passed over the plate 148 and beneath thepresser-foot with its edge in contact with the guiding edge 510. As themachine is put in action, the swinging gate 38 is oscillated in theusual manner in opposite directions transversely of the line of feed ofthe material, thus causing the needle to pierce each material atalternate descents. 1n the present instance, as the needle-bar iscarried to the left the needle is caused to penetrate the main or bodyportion of the material 160, and when the needle-bar is moved to theright the needle is caused to penetrate the rattling strip 156, andowing to the action oit the -rutiling blade being controlled by theswinging gate, the rutiiing blade is moved back or away from the needlewhile the stitches are being formed in the material 160, and in thedirection of the needle to form the gathers as the stitches are beingformed in the rufflingstrip 156, thus causing a plait to be laid in theruiiling strip just before the needle penetrates such strip to form thestitch.
